Flex Fuel Capable
To harness the power of ethanol, Ford has designed flexible fuel vehicles (FFVs). FFVs are "flexible" because you can fill them up with E85 (a blend of 85% ethanol and 15% gasoline), regular gasoline or a combination of the two.
The best part about driving an FFV is that it doesn't require a lifestyle change. Just fuel up with E85 or regular gasoline—whichever is more convenient.
E-Series offers flexible fuel capability with the 4.6L and 5.4L V8 engines.
